Biostar revives old GPUs for modern multi monitor setups

Biostar has introduced a strange but useful set of graphics cards aimed at people who need many displays without paying for high end GPU power. Instead of using modern gaming chips, the company is bringing back older NVIDIA and AMD GPUs and pairing them with four or six HDMI outputs.

The idea is simple. Not every multi monitor setup needs a powerful graphics card. Workstations, control rooms, office systems, trading desks, monitoring dashboards, AI terminals, and digital signage setups often need more display outputs than gaming performance. For those systems, an older low power GPU with several HDMI ports can make more sense than an expensive modern card.

Biostar’s first option is based on the NVIDIA GeForce GT 730. It uses a single slot design, runs without an external power connector, and is fully passively cooled. That means it has no fan noise, which makes it useful for quieter office or display systems. The card includes 4GB of GDDR3 memory on a 64 bit bus and provides four HDMI ports.

Biostar is turning older GPUs into practical display cards

The second card is based on AMD’s Radeon RX 550. This model also offers four HDMI ports, but it uses 4GB of GDDR5 memory and a wider 128 bit bus. Unlike the GT 730 model, it has a single fan cooler, though it still uses a single slot design and does not need an extra power connector.

The most powerful option is the Radeon RX 580 6HDMI. This card uses AMD’s older Polaris GPU with 8GB of GDDR5 memory, a 256 bit bus, and six HDMI outputs. It comes in a compact Mini ITX style board with a dual slot cooler and a single fan. It does need one 6 pin power connector, which makes sense because the RX 580 is much more capable than the GT 730 or RX 550.

These cards are not meant for modern gaming. The GT 730 is far too old for that, and even the RX 580 is now well past its prime for new titles. But that is not the point. Biostar is targeting a niche where output count, low cost, and simple installation matter more than raw frame rates.

The RX 580 6HDMI could be especially useful for users who want a six screen setup from a single card. Many modern GPUs have only three or four display outputs, and some professional multi display cards can be expensive. Biostar’s approach gives buyers another option, especially if they only need HDMI monitors and basic acceleration.

Biostar also showed a more premium product at Computex: the Z890 Valkyrie S motherboard. This is an updated version of its earlier Z890 Valkyrie board, now with an all gold design and a high end layout for Intel Core Ultra Series 2 processors.

The board uses a large VRM setup powered by dual 8 pin CPU connectors. It has four DDR5 slots with support for up to 256GB of memory, along with power and reset buttons directly on the board. Expansion includes three PCIe x16 slots, with at least one Gen5 x16 slot, plus six M.2 slots with heatsinks.

The Z890 Valkyrie S also includes a DIY friendly EZ Release system for the main PCIe slot and easier access to M.2 slots. Rear connectivity includes USB4, Wi Fi 7, Bluetooth 5.4, multiple USB Type A ports, dual HDMI, DisplayPort, 5GbE and 2.5GbE LAN, and a dedicated USB port for BIOS updates.

The design is clearly meant to stand out. The gold heatsinks cover much of the board, and the Valkyrie faceplate on the rear I/O area includes lighting. Pricing has not been confirmed, but this is likely to be a premium motherboard.

Biostar’s Computex lineup is unusual, but that is what makes it interesting. The multi HDMI GPUs serve a practical niche that bigger brands often ignore, while the Z890 Valkyrie S shows the company still wants attention in the enthusiast motherboard space. The old GPUs may not excite gamers, but for people building multi display systems, they could be exactly the kind of simple hardware that still has a place in 2026.
